US4195986A Selective reduction of nickel laterite ores

To prepare nickel laterite ore for selective reduction of its nonferrous metal oxides, it is comminuted (preferably to 85% minus 200 mesh) and is mixed with comminuted (preferably minus 65 mesh) high volatile, high ash waste coal and a non-gaseous sulfur material. Carbon content of the coal is 50% to 150% of the amount of carbon needed for stoichiometric complete reduction of nonferrous

Making Ferronickel from Laterite Nickel Ore by Coal

Nickel was an important material for the production of austenitic stainless steel, heat resistant steel and nick-el-based superalloy [1] [2]. For a long time, the nickel was mainly extracted from nickel sulfide ore [3] [4]. As the exhaustion of nickel sulfide ore in China, developing the resource of laterite nickel ore with low nickel grade

Nickel — Wikipedia Republished // WIKI 2

Nickel is preeminently an alloy metal, and its chief use is in nickel steels and nickel cast irons, in which it typically increases the tensile strength, toughness, and elastic limit. It is widely used in many other alloys, including nickel brasses and bronzes and alloys with copper, chromium, aluminium, lead, cobalt, silver, and gold ( Inconel, Incoloy, Monel, Nimonic ).
